FLYER PBESSER Application filed November 17, 1981. Serial No. 575,676.

This invention relates to flyer pressers used in the preparation of textile fibres for placing the slub or rove upon a bobbin. More particularly this invention effects an improvement in the flyer presser with the object of minimizing the losses in operation that result from amming or breaking of the yarn or rove as it is guided through the flyer.

In the operation of winding bobbins it is customary to feed thread, for example, along one arm of the flyer, a Y-shaped body that rotates around the bobbin. In some types of flyer this arm is constructed as a solid rod along the length of which is a groove to guide the thread. In other types, this arm of the flyer is hollow and through it the thread is passed to the free end of the arm. In this latter type it is customary to provide a narrow slit to facilitate the placement of the thread.

It is customary also to provide the attachment, known as a flyer presser, at the free end of the threaded arm of the flyer. This attachment comprises a finger rotatable about that arm and serving to guide and to tension the thread inwardly toward the bobbin about which the flyer revolves as a whole. The flyer presser essentially is pivoted at the end of the threaded arm of the flyer but often is extended upwardly from this pivot to embrace the flyer arm in a hearing at some hi her point also.

t is to the construction and operation of an improvement in flyer pressers of these general types that this invention is directed. It is an object of this invention to operate and to construct such flyer pressers so that the thread, rove or the like will not be interrupted in its passage by jamming and breaking at the openings, hearings or grooves of the flyer arm and presser. Specifically this invention is directed to obtaining such cooperation between the flyer and the flyer presser that the thread may not balloon, or accumulate such slack as to become entangled in the presser bearing nor to rise along the groove or slot of the threaded arm and become involved in the rotating parts b reason of the dust and lint that collect. further object of the invention is the provision of means to facilitate threading the flyer.

In an embodiment of this invention selected for the purpose of a specific illustration, there are provided one or more fingers extending inwardly below the presser bearlng, these fingers constituting anti-ballooning means, or means to limit the accumulation of slack in the thread and to prevent the rising of the thread to a position where it could become entangled in the resser bearing or could leave the guide in the yer arm. One form is found in the provision of two such fingers depending from the presser bearing, their free ends inclined toward each other. Preferably between the extremities of the fingers a narrow opening is left suflicient for the passage of the material being wound when guided inwardly between the converging fingers in threading the flyer.

The above and other features are described and claimed in the following specification and claims and illustrated in the accompanying drawings, in which:

Figure 1 represents a front elevation of the flyer and presser;

Figure 2 represents a side elevation of the lower part of the presser and the thread carrying arm of the flyer; and

Figure 3 represents a bottom view of the thread carrying arm of the flyer, and the presser with the thread protecting fingers re ferred to.

In these drawings numerals 1 and 2 respectively designate the balance arm and the hollow or slotted thread guiding arm of the usual flyer. Numeral 3 designates the usual tension bar parallel to the arm 2 and adapted to rotate partially around said arm. The usual presser finger 4, is shown extending inwardly at right angles from the lower end of the supporting rod 3.

The junction of the presser finger 4 with the lower end of the supporting rod 3, is shown as a band 5, partially encircling the end of arm 2 to provide swivel play of the presser about said arm 2. An opening left in this partially encircling band or swivel bearing normally is toward the outer face of the fiyer arm 2, approximately opposite the usual guide slot or groove 10 found in that arm. The limits of rotation of the presser and of the position of this opening in the swivel band will be determined in a simple way by lugs 6 at the upper bearing of tension arm 3, such lugs being either integral with the structure of the arm and bar or secured to them.

Usually in the operation of flyers of this type there occur frequent breaks in the material being wound. It is found that this is a result of the thread leaving the slot or groove 10 of the arm 2 or becoming entangled in the lower swivel bearing of the presser finger or becoming caught with the dust and lint that accumulate along the guiding groove of arm 2.

This invention is directed to preventing the thread from ballooning, or in other words, from leavin the groove at the bottom of the arm 2 in its passage to the presser finger and to prevent its becoming entangled in the swivel bearing at the end of arm 2.

For this purpose one or more fingers 7, constituting anti-ballooning means, are secured to the band 5 near the end or ends where the band is left open opposite the thread groove at the end of arm 2. In the illustration shown two such fingers are shown. These extend downwardly and then turn inwardly at approximately right angles to below the center of arm 2, converging so that the free ends of these fingers 7 nearly meet at opening 8 therebetween, and are spaced from the presser. The dimensions of these fingers will vary according to the circumstances of a given situation. For illustration they may be taken to extend clownwardly below the end of arm 2 a quarter of an inch and then turn inwardly the same distance, while their horizontal portions converge to a thirty-second of an inch opening. Obviously the nature of the material treated will introduce variations requiring but ordinary skill.

. A further variation of the embodiment shown would be had by extending the fingers downwardly, but minimizing or eliminating the inward horizontal extension, and causing the downward portion to comprise the narrow slot for threading.

Likewise the mode of attachment of the fingers 7 to the band 5 will vary. They may, for example, be cast integrally with the presser or may be welded, soldered, forged,

bolted or screwed to the band 5. They may be so attached to flyers already constructe It is clear that in operation the thread passes from the bottom of the arm 2 out along the resser finger, and that any slack or deviation of the thread at that point will be fended or warded by the fingers so that the thread may not leave the guiding slot or groove of arm 2, nor rise to a-point where it would be caught in the swivel bearing formed by band 5 about the end of arm 2. Preferably the opening 8 will be thrown a bit to one side of the groove 10, by adjustment of the fingers 7 or by the construction of the lugs 6 to attain that result when the fiyer is in operation.

Other embodiments of my invention would comprise forming the fingers of difierent lengths and placing the opening at some other point than below the center of arm 2. And since this opening is to facilitate threading the presser finger, the opening 8 may be reduced or enlarged in certain embodiments of the invention without losing the advantages resulting from preventing the breaking of the thread due to the placing of the guide as contemplated by this invention.

Likewise it will be clear that other forms of a unitary finger than that last described may be adapted within this invention to the purpose of preventing the deviation of the thread to a point where it may break. It is apparent from this description and the drawings that by this invention the thread is hindered from rising above the bottom of the. groove or slot 10 and from reaching the level of the bearing formed by band 5. By thread is meant also yarn, rove or any other filament material as may be passed through flyers of the type described.
